4. Setup & Installation
Proper installation is crucial for the performance and safety of your ESC. Follow these steps carefully:
4.1 Wiring Connections
- Connect the ESC's three black motor wires to your motor's connectors. The order of connection determines the motor's rotation direction.
- Connect the ESC's black-red-white 3-pin signal wire to your receiver's throttle channel (usually channel 3).
- Ensure all connections are secure and insulated with heat shrink tubing.

4.2 Mounting the ESC
Choose a location that has good airflow to offer best cooling to prevent overheating. Do NOT cover the side with the flat heat shield with hook and loop tape or any other material as this will greatly lower its effectiveness. Mount the ESC with a combination of hook and loop tape or 2-sided foam tape.

5. Operating Instructions
Always perform throttle calibration before the first use or if you change your transmitter.
5.1 Throttle Calibration
- Turn on your radio and keep the throttle stick to the top position.
- Connect the battery pack to the ESC. Wait for about 2 seconds, the motor will beep twice, then pull the throttle to the minimum position. The motor will also beep, which indicates that your ESC has got the signal range of the throttle from your transmitter.

5.2 Programming the ESC
The ZTW Mantis Slim ESC can be programmed using a ZTW Beatles series programming card or directly via your transmitter.
5.2.1 Using an LCD Program Card
- Unplug the ESC throttle cable from the receiver.
- Insert the LCD Program Card G2 into the ESC's throttle cable port.
- Connect the ESC to the battery.
- Wait for the LCD screen to display the power-on interface.
- Press the "ITEM" or "OK" button to enter the parameter setting interface.
- Use the navigation buttons to select parameters and adjust values.
- Upon completion of programming, press the "OK" button to save the parameters.

5.2.2 Setting SMR (Switch Motor Rotation) Function
The SMR function allows you to change the motor rotation direction. It is only allowed to be used when the aircraft is landing on the ground, and it can effectively shorten the landing distance of the aircraft.

6. Maintenance
To ensure the longevity and optimal performance of your ZTW Mantis Slim ESC, follow these maintenance guidelines:
- Keep the ESC clean and free from dust, dirt, and moisture.
- Regularly inspect all wires and connectors for signs of wear, damage, or loose connections.
- Ensure adequate airflow around the ESC during operation to prevent overheating.
- Store the ESC in a dry, cool environment when not in use.
7. Troubleshooting
If you encounter issues with your ESC, consider the following common troubleshooting steps:
- No Motor Response: Check all wiring connections, ensure the battery is charged, and verify throttle calibration.
- Erratic Motor Behavior: Recalibrate the throttle. Check for loose motor wires or damaged connectors.
- Overheating: Ensure proper airflow around the ESC. Reduce load if possible.
- ESC Beeping Continuously: Refer to the ESC's beep codes (if available in a separate manual) to diagnose the issue, often related to low voltage or signal loss.
8. Safety Information
Always prioritize safety when operating RC equipment. Failure to do so may result in property damage, injury, or death.
- Always connect the battery to the ESC last and disconnect it first.
- Ensure the throttle stick is at the lowest position before connecting the battery.
- Keep hands and loose clothing away from rotating propellers.
- Operate RC aircraft in open areas, away from people, animals, and obstacles.
- Never operate damaged equipment.
- Always observe local laws when you fly a RC aircraft or other RC vehicles.
